When I try to use my Wi-Fi signal from my Encore Technologies router for my Nokia Lumia 520, the signal can go from shaky to almost dead yet if I take it down the road to an open signal, the connection is perfect. Are there any suggested settings I can make to my router to fix this problem?

I didn't know anything about that Found the file and uploaded it successfully.Just browsed through the Facebook app which went well, hope it continues to browse normally.Many thanks! Any other suggestions or does that about cover it?
